Application filed 'liugust 7, 1917. Serial No. 184,843.

vented certain new and useful Improve ments in Attachments for Barrel-Wmdlassing Machines, of which the following is a specification.

In windlassing a barrel, to position the truss hoop onthe end thereof, it is at present the custom to loop a rope or cable around the barrel a short distance below the end thereof, and draw the rope or cable ends "in opposite directions, thus drawing the barrel stave ends together; by this method uneven pressures are applied tothestaves and some staves'are subjected to a side strain, due to the friction of the rope or cable over the surface thereof, and an unsymmetrical barrelis the result.

Ourpresent invention relates to an attachment designed for use in connection with win'dlassing machines for'windlassing barrels, and by the employment of which, the windlassing rope or cable is guided, the speed of bending the stavesis equalized and the edges thereof are brought in contact at the same time, thus insuring a symmetrical barrel. The use of the attachment also eliminates undue compression and friction at the point ofcrossing ofthe windlassing rope or cable and gives a truly round circumference to the barrel overcoming the necessity of leveling the barrel after windlassing and before trussing.

The invention consists primarily in providing a flexible spring member, bent to a radius slightly greater than that of the barrel to be windlassed and of a'length to extend half way around the same, the spring member being provided with cable or rope guides for receiving the cable or rope passing around the barrel and longitudinally of the spring, the tightening of the cable by drawing the opposite ends thereof in opposite directions drawing the edges of the barrel staves together at the same time.

iVith the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein:

Figure l is a view in plan of the preferred embodimentof our invention.

Fig. 2 is a view in side elevation, with a barrel positioned within the spring arms and illustrating the win'cllassing tightly encircling'the same.

Fig. 3 is a view in plan, of the construc tion and arrangementillustrated in Fig. 2.

Fig. at is a'centrall sectional view through the support.

Fig. 5 is an enlarged detailed plan view of the spring arms, support, and windla-ssing rope or cable guide.

In the drawings, wherein like characters of reference designate corresponding parts throughout the several views, 1, indicates a I suitable support to which is attached in any suitable manner, one end of a bracket 3, substantially T-shaped in plan. The outer surface of the bracket head 4, which is slightly curved, is provided with a longitudinal recess 5, in which is received the central portion of the yieldable curved guide member 6, preferably of spring matcrial. The guide member is removably secured within said recess of the supporting means, and the radius of the curve of said guide isslightly greater than that of the barrel to be windlassed and said yieldable guide is of such length as to extend approximately half way around the windlassed barre y The guide member 6, is preferably reduced in thickness from its center toward its opposite 'endsand the rear face of each end of said guide is provided with a suitable eye 9, through which pass the Windlass rope or cable 10, portions of which cross at A within the bracket 2 and pass through a transverse guide 11 therein.

By crossing the rope or cable 10, as at A, a loop B for encircling the barrel end, as in Figs. 2 and 3 of the drawings is provided.

The opposite ends of the Windlass rope or cable 10 are secured to any suitable form of pulling means commonly employed in barrel windlassing machines, and when tension is applied to said opposite ends the portion of the loop B extending beyond the arm 6 is cable I V crossing point A is overcome.

windlassed and passing the windlass rope or cable over the exterior of the sa1ne,,the frictional contact between the Windlass rope or cable and the barrel staves adjacent to the The spring of the guide 6 expands the loop B around the barrel on the release of tension from the 7 ends of the Windlass rope or cable 10 enabling the Windlass barrel to be easily removed therefrom, and a barrel to be windlassed to be placed in its position.

Having thus described our invention, what we claim is 1. An attachment for barrel windlassing machines, comprising a fixed support, a yieldable rope or cable guide member secured thereto, and curved to partly embrace a barrel, said guide provided with rope or cable guide openings through which the Windlass loop forming cable or rope passes prior to crossing at a point within said fixed support.

2. An attachment for Windlassing machines, comprising a fixed support, a yieldable Windlass rope or cable guide member secured thereto, with its opposite ends promachines, comprising a support, a spring arm extended from the opposite sides thereof in opposite directions to lie in a substan.

tially horizontal plane andrigidly secured to'said support, said arms bent or curved to embrace a barrel, and of a length to extend approximately half way around the same, a,

Windlass rope guide carried on the rear surface of each arm adjacent its free end, and 7 said support provided with an opening through which the crossing portions of the Windlass loop forming rope or cable pass.

'5. An attachment for barrel windlassing machines, comprising a fixed support, a member detachably secured to the face thereof and providing a flat spring arm extended.

from the opposite sides thereof in opposite directions to lie in a substantially horizontal plane, said arms tapering from their inner to their outer free ends and bent or curved to embrace a barrel, said arms being of alength to extend partly around a barrel, an eye carried on the rear surface of the free end of each arm and through which the loop forming portions of the Windlass rope pass, said support provided in the rear of said spring arms with an opening through which the crossing portions of the Windlass loop form- 7 ing rope or cable pass, said eyes and open ing arranged in alinement causing the rope to pass exteriorly of thespringarms and to lie in contact with the outer face thereof.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
